Abstract

PROBLEM TO BE SOLVED: To enhance the adhesion of a bonding resin to tiles of a tile unit which is obtained by connecting the adjacent tiles together with the bonding resin, by forming fine rugged portions on surfaces of each tile to which the bonding resin is stuck. SOLUTION: Fine rugged portions are formed on surfaces of each tile 1 extending from a lower portion of a side surface to a portion of a rear surface near the side surface. The rugged portion 2 has its surface roughness set to about 100 to 500 μm in terms of a center line mean roughness, to which a bonding resin 32 is stuck. Further, a cross angle of the side and rear surfaces of the tile 1 is made into a chamfered slant surface on which the rugged portion 2 is formed, and then the bonding resin 32 is applied thereto. Still further, a reentrant is formed in the side surface of the tile 1, in which the bonding resin 32 is filled. The reentrant has a dovetail cross section or a semicircular cross section. Therefore, the adhesion of the bonding resin to the tile is enhanced, and the handling of the tile unit is facilitated.

SUMMARY OF THE INVENTION An object of the present invention is to increase the adhesion of the connecting resin to the tile.

[0005]

SUMMARY OF THE INVENTION According to the present invention, in a tile unit in which a plurality of tiles are arranged in parallel and adjacent tiles are connected by a connecting resin, means for increasing the adhesion of the connecting resin to the tiles. It is characterized by having.

The following are examples of means for increasing the adhesive force. (1) Fine irregularities are provided on the surface of the tile where the resin for connection is attached. (2) A concave portion is provided on the side surface of the tile to allow the coupling resin to enter. (3) On the back surface of the tile, a recess is provided separately from the back groove, into which the connecting resin enters. This recess may face the side of the tile. The recess may face both one side of the tile and another side adjacent to the side. The recess extends in a substantially U-shape or a U-shape, and may face two sides with respect to one side surface. The recess may have a portion facing the side surface narrower than a portion separated from the side surface. (4) A groove is formed in which the intersection corner between the back surface and the side surface of the tile, into which the coupling resin enters, is missing.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional view of an end of a tile 1 of the tile unit according to the first embodiment. FIG. 2 is a sectional view of a tile unit using the tile 1.

The tile 1 has a lower portion on the side surface (near the back side).
And the vicinity of the side surface of the back surface, the fine irregularities 2 are formed, thereby increasing the adhesive force between the connecting resin 32 and the tile 1 in the tile unit. This unevenness 2
It is preferable that the surface roughness is about 10 to 1000 μm, especially about 100 to 500 μm in center line average roughness.

FIG. 3 shows that the intersection angle between the side surface and the back surface of the tile 1a is a chamfered slope, and the unevenness 2 is formed on the slope. The tile unit using the tile 1a is also connected to the tile 1a. Adhesive force with the resin 32 for use becomes high.

FIG. 4 is a cross-sectional view of the tiles 1A, 1B, and 1C provided with concave portions on the side surfaces of the tile where the connecting resin 32 enters. In the tile 1A of FIG. 4A, the concave portion 3 has an ant-shaped (a shape with a narrow entrance and widening in the back), and in the tile 1B of FIG. 4B, the concave portion has a semicircular cross-section. In the tile 1C of FIG. 4C, the cross section of the concave portion is a square hole.

The recess may be an independent small hole as shown in the hole 3 'of the tile 1' in FIG.
It may be a groove extending in the side direction of the tile like the groove 3 "of the tile 1" of (b). Note that a plurality of recesses formed of small holes may be provided. The length of the groove may be shorter than that shown.

FIG. 6 is a sectional view of a tile unit using the tile 1C. As shown in the figure, the connecting resin 32 has the concave portion 3.
By entering into B and 3C, the adhesive force between the connection resin 32 and the tile 1C becomes extremely high. Although not shown, the same applies to other tiles.

FIGS. 7 to 12 show a tile of a tile unit in which a concave portion facing the side surface of the tile is provided, and the connecting resin 32 is inserted into the concave portion.
0 is a perspective view from the back side, FIG. 11 is a back view of the tile, FIG.
FIG. 12 is a perspective sectional view taken along line XII-XII in FIG. 11.

The tile 4 shown in FIG. 7 has a rectangular recess 5, the tile 4A shown in FIG. 8A has a trapezoidal recess 5A, and the tile 4B shown in FIG.
Is provided. The recesses 5A and 5B have a narrow width at the entrance side facing the tile side surface, and have extremely high adhesion between the connection resin 32 and the tile.

The recesses 7, 7 of the tiles 6, 6A in FIGS.
A is a groove. The concave portion 7 starts from one side and returns to the side, and may be U-shaped (may be U-shaped).
Consisting of grooves. The recess 7A in FIG. 10 is a substantially quadrant arc-shaped groove starting from one side and entering the side adjacent thereto, but may be an L-shaped groove.

In FIG. 11, a concave portion 9 is provided which is formed by a groove which cuts off an intersection between the side surface and the back surface of the tile 8.
When the connecting resin 32 enters the concave portion 9, the adhesive force of the connecting resin to the tile is increased.

The above embodiment is an example of the present invention, and it is apparent that the present invention may have a configuration other than the above.

[0018]

As described above, the tile unit of the present invention has a high adhesive force between the tile and the connecting resin, so that the tile unit can be easily handled. In addition, tiles do not fall off from the tile units during the work at the construction site, and the efficiency of tiling work is improved.
